Retired Navy pilot David Fravor said that in 2004 off the coast of Southern California, advanced radar detected what operators called "multiple anomalous aerial vehicles" descending 80,000 feet in less than a second.

Congress is starting to take “Unidentified Aerial Phenomena” seriously.

The Senate majority leader really wants the public to know what’s out there.

A Pentagon official who heads up a secretive unit studying unidentified flying objects has speculated that recent sightings in US airspace could actually be alien probes from a mothership sent to study Earth.

Something else is going on.

A Harvard University astronomer and the head of the Pentagon’s UFO office teamed up to release a draft paper saying that interstellar objects detected in space could be signs of extraterrestrial life, but current sky-mapping technology could miss such objects. NBC News’ Gadi Schwartz has the story.

The agency says it was a mistake, but how did this flying saucer logo get uploaded in the first place?

NASA isn't taking its coming UFO investigation lightly. The agency announced in June that it will open a scientific study into UFOs (short for "unidentified flying objects"), or, as they've recently been rebranded, UAP ("unidentified aerial phenomena"). The main goals, NASA officials said at the time, will be to identify and characterize the available UFO data, lay out the best ways to collect observations in the future and determine how the agency can use such data to advance our understanding of these puzzling sky sights.

A Harvard professor thinks very seriously that a meteor that fell to Earth in 2014 could contain alien technology – which would explain its surprising resistance… In the United States, doing serious research on extraterrestrials no longer seems taboo. Researcher Avi Loeb, a well-respected man in Harvard’s astronomy department, has just announced plans to mount a mission to retrieve fragments from a meteor that crashed into the Pacific Ocean in 2014.

Although modest in scope, a NASA research project reflects shifting attitudes toward the formerly taboo subject of UFOs

Today, NASA announced that it is putting together an independent team of researchers this fall to study sightings of unidentified aerial phenomena, or UAPs, the updated term now used to refer to UFOs. The space agency says it plans to study these sightings from a scientific perspective but also stressed that “there is no evidence UAPs are extra-terrestrial in origin.”

The proceedings begin at 9 a.m. EDT (1300 GMT).

1,500 pages of UFO related research were just declassified as part of a FOIA request.

A response to a FOIA request has revealed the Library is setting on a possible treasure trove of documents about UFOs.

VICE World News obtained nearly 300 pages of documents through freedom of information requests that include strange sightings from pilots, soldiers, and police officers.

Interest in UFOs continues to grow, both among scientists and government officials.

The U.S. government hasn't comprehensively studied UFOs in decades — but not all ufologists are excited about a new Pentagon investigative office.

The nine-page preliminary US government report released last June is only supplemented by an additional eight classified pages according to a report by The Black Vault

The U.S. government released its highly-anticipated report UFO report and was met with what can only be described as a lackluster response.
